fix: patch masked replace textures and text reveal speed

[han4wluc]

Summary

• bump the package patch version from 1.7.2 to 1.7.3
• force masked replace shader render textures to use logical-resolution textures (resolution: 1) so mask sampling stays stable
• make text-revealing render immediately at speed: 100, remap animated speeds onto a curved 0-99 scale, and add unit + VT coverage for the new speed behavior

Testing

• vitest run
• bun run build
• docker run --rm --user $(id -u):$(id -g) -e RTGL_VT_DEBUG=true -v "$PWD:/workspace" docker.io/han4wluc/rtgl:playwright-v1.57.0-rtgl-v1.1.0 rtgl vt screenshot --wait-event vt:ready --item textrevealing/text-revealing-speed-scale.yaml --item rendercompleteevent/render-complete-text-revealing-speed-100.yaml
